Unreal Development Kit Game Programming with UnrealScript: Beginner's Guide

By: Rachel Cordone

Overview of this book

Unreal Development Kit is the free edition of Unreal Engine—the largest game engine in existence with hundreds of shipped commercial titles. The Unreal Engine is a very powerful tool for game development but with something so complex it's hard to know where to start.This book will teach you how to use the UnrealScript language to create your own games with the Unreal Development Kit by using an example game that you can create and play for yourself. It breaks down the UnrealScript language into easy to follow chapters that will quickly bring you up to speed with UnrealScript game programming.Unreal Development Kit Game Programming with UnrealScript takes you through the UnrealScript language for the Unreal Development Kit. It starts by walking through a project setup and setting up programs to write and browse code. It then takes you through using variables, functions, and custom classes to alter the game's behavior and create our own functionality. The use and creation of Kismet is also covered. Later, using replication to create and test multiplayer games is discussed. The book closes with code optimization and error handling as well as a few of the less common but useful features of UnrealScript.

Time for action – Components as variables


As our new AwesomeInfo class doesn't have any subclasses, we can mess around with it without worrying about breaking anything, so let's keep working there.

  1. First, we're going to put a StaticMeshComponent in the class, similar to what we did with our AwesomeEnemy class. Let's rewrite our AwesomeInfo class to look like the following code snippet:

    class AwesomeInfo extends Info
        placeable;
    
    defaultproperties
    {
      Begin Object Class=StaticMeshComponent Name=MyMesh
        StaticMesh=StaticMesh'UN_SimpleMeshes.TexPropCube_Dup'
        Materials(0)=Material'EditorMaterials.WidgetMaterial_Y'
        Scale3D=(X=0.25,Y=0.25,Z=0.25)
      End Object
      Components.Add(MyMesh)
    
      bHidden=false
    }
  2. As we're using an emissive material, we don't need to set a light environment for the StaticMeshComponent. The Info class has bHidden set to True, we need to change it so we can see the AwesomeInfo in game.

  3. Compile the code, and open AwesomeTestMap in the editor.

  4. If the AwesomeActor is...
